WINDING AND SPOOLING APPARATUS.

Specification of Letters Patent.

Application filed October 22, 1908.

Patented May 4, 1909.

Serial No. 459,087.

To all whom it may concern:

is journalcd a shaft B having -fixed to and Be it known that I, JanosSonlinnrr extending axially therefrom a spindle 1 for NUSSBAUMER, acitizen of the Republic of the winding spoo s. The shaft is driven bySwitzerland, residing at Erlenbach, near Zurich, Switzerland, haveinvented certain new and useful Improvements in Wmdmg and SpoolingApparatus; and I do hereby declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same,reference being had to the accompanying drawings, and to letters orfigures of reference marked thereon, which form a part of thisspecification.

In winding and spooling thread (which term I here employ in its generalsense, intending therefore to include yarn) from bobbins, reels, orsimilar thread-delivering contrivances (hereinafter briefly referred toas bobbins), it frequently happens that owing to knotting, tangling, orjamming of the thread, or, in the event of the bobbins being wound inbulged form, owing to variation in diameter, the pull on the thread istemporarily increased, whereupon on the cause of such abnormal pullbeing overcome, the bobbin has the tendency to race, that is rotate inadvance of the thread. Attempts have been made to remove this drawbackby the provision of spring-mounted rollers, over which the unwoundthread is guided. Such arrangement, however, is useless in the event ofthe thread breaking.

For the purpose of providing regulation even in the event of breakage ofthread, I furnish for the bobbin an oscillating appliance which isinfluenced by the pull of the thread and serves to brake the bobbin, thebraking action, however, being overcome again by the pull of the thread.Thus in the event of a sudden diminution of tension after increased pullof the thread, and also on cessation of the pull altogether, theappliance exerts a braking action on the bobbin and thus prevents racingof the latter.

One form of construction of the invention is illustrated in theaccompanying drawing, in which Figure 1 is a side elevation, and Fig. 2a front elevation of a duplex spooling machine. In the followingdescription only one of the two devices shown will be considered, asboth act in precisely the same manner.

In the construction shown in said drawings A designates a suitablebolster in which any suitable means such as a gear wheel I) fixed on oneend and adapted to mesh with and be driven by a similar gear, not shown,on a suitable motor.

Mounted on and extending above the bolster A is a standard O having anarm 6, projecting at right angles thereto, to which latter is secured abracket 0 in which is journaled a compensating pulley l yicldingl heldagainst lateral movement by a spring o A short standard I) is mounted onthe bolster A parallel to the standard O and has a horizontal pin (Zfixed in its upper end on which is ournalcd a pulley 3.

Bolted or otherwise connected with and depending from the arm 0 is aframing in the form of a yoke comprising two parallel arms 4 in thelower ends of which is journaled an axle 5 carrying a thread containingmember 6 fixed thereto. Projecting from the inside of the arms 4 abovethe axle 5 are pins 7 on which is pivoted a cradle 8. On the end of thelatter nearest to the standard O is suspended a weight 9 adapted tonormally hold the opposite end of the cradle elevated above the plane ofthe thread container 6. In said elevated end is fixed apin 8 projectingparallel to the axle 5 serving as an axle for a roller 10. On one sideof the cradle S is fixed a projection 11 adapted to serve as a brakeshoe for the axle 5, said projection being fixed at a distance from theaxis of pin 7 to swing in the arc of a circle which if struck from saidaxis as a center would pass through the axis of axle 5. The engagingface of the projection is preferably recessed or concaved to conform tothe periphery of the axle for the purpose of increasing the size of theengaging surface of the shoe. thread runs from the container 6 overroller 10, pulleys 3 and 2 to the spool spindle 1.

The a If, now, at the bobbin 6 the pull of the thread I axis 5 and exerta braking action upon it, framing, having an arm extending paralleluntil the extent of draft of the thread is 1 to the spindle adapted toform athread guide again normal, or until the thread has been l andmeans on said support forming a brake pieced-up again.

Since the braking takes place directly at the bobbin, it is possible tovery greatly increase the speed of the latter. The cradle 8 mayobviously also be so constructed that both its limbs exert a brakingaction on the bobbin or its axis.

It is clear that the same braking device can also be employed for reelsor the like, as well as bobbins.

Having now particularly described and ascertained the nature of my saidinvention and in what manner the same is to be performed, I declare thatWh at I claim is:

1. In a winding or spooling apparatus in which is combined a framing, athread containing member mounted therein, a rockable support pivoted inthe framing, a thread guide mounted on the support parallel to thethread containing member, said support adapted to serve as a brake forthe thread containing member.

In a winding or spooling apparatus in which is combined a framing, arotary spindle journaled therein, a bobbin fixed on the spindle, agravitating support pivoted in the for the spindle.

3. In a winding or spooling apparatus, in combination, framing, a bobbinmounted thereon, a gravitating cradle pivoted to the framing, whose onelimb constitutes a brake for the bobbin, and a thread-roller mounted 1on the cradle above its pivotal points, substantially as described.

l. In a winding or spooling apparatus, in combination, framing, a bobbinmounted thereon, a U-shaped cradle having its vertical arms pivoted tothe framing above the bobbin and located contiguously to the axis of thelatter, and its horizontal loaded end located below the level of thebobbin, and a thread-roller mounted on the cradle above said bobbin andparallel with it, substantially as described.

In testimony that I claim the foregoing as my invention, I have signedmy name in presence of two subscribing witnesses.
